Hot refueling operations are not allowed within how many feet of any building unless operating under a waiver from CG-41?

• A. 50 FT
• B. 150 FT
• C. 200 FT
• D. 100 FT

Answer: (D)

Hot refueling carries a significant fire risk because fuel vapors can ignite and ignition sources may be near buildings. To reduce that hazard, a safety buffer from structures is required unless a CG-41 waiver is in effect. The mandated distance is 100 feet, balancing effective vapor dispersion and practical operations. A smaller distance, like 50 feet, would be unsafe, while larger distances such as 150 or 200 feet are more conservative than necessary.
